Page 86 - When testing, the vertical distance from the surface of the water to the center of the pump suction inlet should not exceed 1 0 feet.
Page 87 - Allowance is made for loss in deluge set; these values will also give approximately correct figures for turret nozzles and water tower, except that in the latter, pressure equal to 0.434 times the height of tower must be subtracted from the engine pressure, before solving for nozzle pressure. , oa ?1 J" i If 'J »| ii <f if 2 Single Line iH
Page 140 - The fact is more impressive, usually, when conversely stated: it requires five times as much heat to raise the temperature of a pound of water one degree as to raise the temperature of a pound of these soils one degree.
Page 161 - The arguments of one class, moreover, are intrinsically more weighty than those of another. Some compel belief irresistibly, others only establish a degree of probability greater or less. It is one of the most common and at the same time most successful arts of sophistry to put off the less for the more weighty, the merely probable for the absolutely demonstrative proof.
Page 75 - ... should, however, be restricted to fires in materials other than oils, except as mentioned in this section. Foam Foam extinguishes oil fires partly by the cooling from the water it contains, but more by cutting off the oil surface from the air, flames, and radiant heat, and retarding the formation of oil vapor necessary for the continuance of the fire. If the oil for a considerable depth below the surface has reached a temperature where vapor is given off freely, the vapor will penetrate the foam...

Page 169 - Horizontal exits consist of swinging doors through or around fire division walls or partitions. Horizontal exits are credited with the same capacity for exit purposes as other doors, but augment by 50 percent the credits allowed other exits leading from protected areas on the side of the wall to which exit is made.
Page 11 - Some firemen prefer to grasp the beams while ascending and descending, while others prefer grasping every rung, or every other rung, with the hands. Use the ball of the foot in climbing, and do not run. Climb steadily and smoothly. The feet should be at the center of the ladder to prevent wobbling. The use of a life-belt (Fig.
Page 16 - ... throwing of a stream over a church spire, city hall or court house does not necessarily show that the engine is capable of delivering its full rated capacity at a proper working pressure. Investigation has shown that where regular and systematic tests of engines are not made, even in well managed fire departments, defects often exist which may continue unsuspected for considerable periods and become manifest under the stress of a large fire, where the engine is called upon to deliver its full...
